Diego Rodrigues de Sa e Souza b38f3a4c02 feat(test:scoped): add TIA-based local test runner (#8084 D1) (#9143)
- npm run test:scoped: runs only tests impacted by your changes
- npm run test:scoped:staged: for staged changes (pre-commit)
- Uses select-impacted-tests.mjs with impact map when available
- Falls back to heuristic (changed test files) when no map
- Hub file changes suggest full suite
- 7 unit tests for the selection logic

# test-scoped — run only unit tests impacted by your changes.
#
# Usage:
# npm run test:scoped # tests for changes vs HEAD~1
# npm run test:scoped -- --staged # tests for staged changes only
#
# This is the local DX companion to the CI TIA gate (#8084 D1). The CI version
# builds a full import-graph impact map; for local dev we use a fast heuristic:
# - Changed test files → run those directly
# - Changed source files → run tests that share the file's directory/name prefix
# - Hub files (tsconfig, package.json, etc.) → suggest full suite
#
# For the full TIA (import-graph based), use: npm run test:scoped:full
# (requires a pre-built impact map via: node scripts/quality/build-test-impact-map.mjs)
